Moral Schizophrenia and the Paradox of Friendship

In his landmark paper, ‘The Schizophrenia of Modern Ethical Theories’, Michael Stocker introduces an affliction that is, according to his diagnosis, endemic to all modern ethical theories. Stocker's paper is well known and often cited, yet moral schizophrenia remains a surprisingly obscure diagnosis. I argue that moral schizophrenia, properly understood, is not necessarily as disruptive as its name suggests. However, I also argue that Stocker's inability to demonstrate that moral schizophrenia constitutes a reductio of modern ethical theories does not rule out the possibility that he has identified a noteworthy psychological phenomenon. Stocker is, in my opinion, correct to note that balancing our broad ethical obligations with authentic personal motives is a non-trivial psychological challenge, even if this challenge is not equivalent to a mental disorder. Hence, I conclude that proponents of modern ethical theorists should not be complacent about the burdens associated with implementing a ‘schizophrenic’ moral psychology.
